KICK-OFF Fon 'sHEARs.

Application filed August a, 1925. Serial No. 48,568.

This invention relates to a new and improved kicker or push off for shears and more particularly, to an apparatus of this character adapted to kick off scrap ends cut off by shears.

Shears are commonly used in Connection with blooming mills for the purpose of shearing off imperfect ends of the blooms and it is desired to kick or push off the crop ends from the roll table. The roll table carries on the sheared blooms for further operation. It is important that such a'kicker or push off be so coordinated with the movement of blooms over the roll table that their movement is not obstructed.

It is an object of the present invention to provide a kicker or push off associated with shears and adapted to selectively push out ends from the roll table.

It is a further object'to providea construction of this character in which the kicker is closely associated with the shear blade, so as to handle crop ends of small size.

It is an additional object to provide such a kicker so related with the roll table drive as to prevent interference of the push off with movement of blooms over thetable.

Other and further objects will appear as the description proceeds.

I have illustrated a preferred embodiment of my inventionin the accompanying drawings, in which Figure 1 is a plan view of'the kick off and portions of the associated shear and roll table, and

Figure 2 is an elevation of construction shown in Figure 1.

The shear comprises the upper jaw 11 carrying the knife or blade 12, this jaw and knife remaining fixed during the shearing operation. It also comprises the lower movable jaw 13 carrying the knife 14. The method of operation of the jaw forms no part of the present invention and need not be described in detail.

It will [be understood that the lower jaw 13;- is raised in the shearing operation so fthatthe edge of the knife 14 passes the edge "oflthe knife 12. The blooms are fed v to the shears by the roll table 15 and carried away by the further extension of the same table. This roll table is driven by the gears 16 sh wn in Figure 2, but as this drive forms no part of the present invention, it need not be described in detail. j i- 1 The kicker, or 'push off comprises the elongated foot 17, the outer end 18 of which liesover the movable jaw 13 and knife 14L This foot 17 is fixedly secured to the rod 1:9. This rod is carried in the bearing 20 and is reciprocated inthat bearing by the slide member 21, which is guided in the I members 22 secured to the side of the shear frame. The end of the rod 19 is secured in the bearing 23 carried by the slide 21 and is free to rotate in that hearing. The'arm 24 is secured to the rod 19 and the spring 25 carried by the rod 26 bears down on the arm 2% and thus holds the extended end 18- of' thefoot down against the movable jaw.

The slide 21 is reciprocatedby means of the connecting rod27 which is pivotally connected to the slide at 28 and similarly connected at 29 to the crank 30. This crank 30 is carried by shaft 31 which is driven through worm gear32 by shaft 33. i The,

shaft 33 is driven by gear 3eiwhich meshes with gear35 driven by motor 36. The motor 36 is controlled by two limit switches 37 and 38, the function of which will be described hereafter.

The limit switch 38 isoperated by the handle 40 The'limit switch 37 is operated by movement of. the gears driven by motor 36 when the kicker isoperated. This switch 37 is connected, by wires 41 and 42to the motor 413, which, through gears 44 and 45, drives the worm46. This worm 46, through worm gear 16, drives the conveyor rolls 15.

As indicated in dotted lines inFigure 1,

the stroke of the pusher foot 17 carries it roll table is then stopped by any suitable control, which has not been shown, and the shears are operated by a shear control to raise the lower jaw and shear off the end of the bloom. As soon as the shearing action has taken place, and either before or after the lower jaw hasreturned to its lower position, the limit switch 38 is operated by means of handle 40. This switch causes the motor 36 to go into operation and thus ,through the gears and the crank 30 forees the kicker foot to the left pushingthe crop end of the bloom off of the roll table and movable shear jaw. This movement of'the crank continues until the crank has made a. complete revolution and the kicker foot is drawn back 'to the full line position qf Figure 1.

The limit switch 37 is in the circuit controll 0f the I drive of ;the roll, table 115., and prevents operation of the table untilithe kicker foot 18-has-returned to the full line position, The switch 37;bre aks the circuit to. m 0tor a -s o th k ke star n ope t on n hi C cu t, is no re or unti h kicker has returned to the rest position.
